What Plants Need to Grow

Plants help many things grow—including us!
What do plants need to grow?

Air
Humans need air to breathe. But plants need air too! Plants take carbon dioxide out of the air. The plants use the carbon dioxide to make sugars and starches that the plant uses as food.

Light
Plants use energy from sunlight to help them make sugars and starches. These sugars and starches are used by the plant to grow and be healthy.

Water
Have you ever seen a plant that wilted? It probably needed water. Like humans, plants need water to grow and be healthy.
